PATRICK MOENTEE, OF MONTGOMERY, MINNESOTA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 451,505, dated May 5, 1891.

Application filed May 17,1890. Serial No. 352,223. (No model.)

To all whom it may concern:

Be it known that I, PATRICK MOENTEE, a citizen of the United States, residing at Montgomery, in the county of Le Sueur and State of Minnesota, have invented certain new and useful Improvements in Oar- Couplings, of which the following is a specification.

My invention relates to car-couplings in which the ordinary link and pin are used.

The principal object of the invention is to provide devices to prevent accidental uncoupling of the cars while in use. This object is accomplished by the devices illustrated in accompanying drawings, in which Figure 1 is a front view of the draw-head and a portion of a car provided with my improvements, and Fig. 2 is a central vertical sectional view of the same.

In said drawings, 1 designates the end portion of the frame of the car.

2 represents the draw-bar, and 3 a drawhead thereon.

In the coupling devices illustrated the pin 4 is lifted out of the pin-hole 5 in the drawhead by means of an angle-plate 6, engaging the head of a pin, and which is connected by a short rod 7 (or a chain) to an arm 8, formed on a rocking rod 9, which is supported in staples 10 on the front end of the car. The rocking rod has a crank 11 at each side of the car for turning it, and a Vertical rod 12, connected to a lateral arm 13, for operating it These devices are similar in character, in a general way, to those disclosed in my application, Serial No. 332,213, filed March 5, 1890.

Other suitable means may, if desired, be employed for lifting the pin.

The pin-hole 5, instead of being vertical, is made at a suitable inclination, preferably about eighty-five degrees to the horizontal plane, and in its forward part is a recess 14, terminating in a shoulder 15 above the opelr ing 16 for the link. When a coupling is to be made, the pin is raised by means of the cranks and the rocking rod, (or other'1neans,) so that its point will rest on the shoulder 15. The pin, being thus seated above the slot 16, is in position to be thrown back into the slot by the jar of the two draw-heads in making the coupling. In the inner end of the linkslot 16 is formed a small recess 17 to permit the end of the link 18 to enter and be held in horizontal position, as indicated in the drawings, thus facilitating the making of a coupling with another draw-head on the same level or a slightly-higher level.

In using links and pins in the ordinary draw-heads the cars frequently become uncoupled while in motion on uneven roadbeds, because the jolting of the draw-heads lifts the pins out of the links. This often occurs where one of the draw heads is higher than the other, so that the connectinglink is in an inclined position and tends to lift the pin in the lower draw-head. By having the pin-hole inclined, as shown, there is no tendency of the link to lift the pin.

As the draw-bars have some play in their slots, there is a tendency on concussion of the heads to rise and fall suddenly, and so displace the pins. I avoid this rising of the draw-head by providing an inclined surface 19 011 the top of the draw-bar and causing this incline to engage asurface 20, which may be a 'plate attached to the under side of the carframe immediately above the draw-bar, and so when the draw-bar is thrust inward the inclined surface slides on the plate, and thebar, instead of rising, is forced downward while it is being driven inward. The bar, being provided with the usual spring, is returned to its initial outer position when disengaged. Thus by means of the inclined pin-hole and the inclined surface on the outer bar I obviate the danger of displacement of the pin from its link while in use.

WVhat I claim is 1. In a car-coupling, a draw-bar having an incline on its upper surface, in combination with a fixed object adapted to engage the incline and depress the bar when the latter is thrust inward, substantially as and for the purpose set forth.

2. In a car-coupling, a draw-bar having an incline on its upper surface, a fixed object engaged by the incline to depress the bar, and a draw-head having a pin-hole inclined forward from top to bottom, substantially as set forth.

3. In a car-"coupling, a draw-head having a pin-hole inclined forward from top to bottom and providing a recess, and a shoulder in the tion between said arm and the pin-holder, and front wall to receive and temporarilysupport cranks for turning the rocking rod, substana pin, substantially as set forth. tially as setforth.
